2) When the automated rail-mounted gantry crane is operating in a bay, the trolley/hoist mechanism should use the best path. The cart/lift mechanism does not have an optimal path and should have a "bowling prevention" protection when the cart begins to move. In addition to this, the spreader only allows the cart to move above a safe height.

3) After the container is placed in the container area of the storage yard and the unlocking is completed, if a new command is not received, the lifting appliance is still stopped on the container for a preset time (default is 5 seconds), and then the lifting appliance is automatically lifted to the highest height. The latency should be variable by adjusting the parameters. During waiting or during execution of the safe altitude movement, new work orders are sent by the automated track crane control system and can be accepted.

4) The lifting appliance is higher than the maximum pile height: when the hoisting/spreader mechanism (or with containers) is operated above a safe height, the trolley/cart speed is not limited. If the trolley is in the correct position and receives the work order, the cart can be run on a track at a safe height. The cart movement will be limited to a small range around the target position given by the work order.

3) In the automatic operation mode, if abnormal conditions of spreader/container positioning occur, an operator can timely intervene in the system, and the operator can be switched to a remote control mode at any time.

4) The RFID card of the card collecting belt is inconsistent with the system; the hub card does not carry an RFID card or the card carried has a fault: under the working conditions, when the storage yard enters, the RFID card reader at the entrance of the storage yard cannot be triggered to normally work, so that the task corresponding to the card collection cannot be activated and cannot be sent to machinery, and the working condition 1 is controlled on the RYECS layer and does not need to be considered by a single-machine equipment control system.

5) The collection card number corresponding to the in-out box task in which the machine is working is not a collection card parked at the working position:

treatment 1: the driver of the operation desk tells the truck driver to drive away the truck by talkback and gives the task truck a position to be driven away.

And (3) treatment 2: the operator of the operation platform clicks a button of an interface provided by the ABB, feeds back the current card collecting number to the interface table, schedules the card collecting number fed back by reading the current task from the interface table, cancels the current corresponding task of the machine (if the task is taken out of the box and the box is grabbed, simultaneously generates a return instruction), then recalculates the priority of all tasks in the task pool, and raises the priority of the operation position stop card collecting to the highest level, and then sends the highest level to the machine.

6) The track crane is abnormally changed into manual work to finish the state feedback problem: if the ABB can manually give a completion state on an operation table interface, the completion can be given in the mode; if ABB does not have the interface, RYECS has an ATmonitor operation interface, and the center control personnel can use the foreground to perform manual simulation to complete feedback.

In the process, the control console can automatically switch on-site images and images of the lifting appliance to a display of the operation console through the video server according to information such as on-site conditions, task types and the like, then an operator can move the lifting appliance up and down to the collecting card or grab a box from the collecting card through the lifting handle, corresponding operation is completed, when the lifting appliance is pulled to a safety height, the control console can automatically complete the task, the display is closed, and the operation is returned to the automatic track crane.

Because the container truck can not stop when the container is automatically taken and packed by the operation table, manual intervention is necessary. The crane therefore comprises a position sensor, the crane being provided with a reference position, and the operating station matches the operating task to the crane when the position sensor has reached the reference position. The crane comprises a plurality of hoisting phases, and the operation platform corresponds the operation tasks to the hoisting phases.
